On AntiRacistAction.org, the group stated the alleged motivation behind the incident:

On Saturday, May 19th a group of 30 anti-fascists descended upon Ashford House restaurant in the Chicago suburb of Tinley Park where the 5th annual White Nationalist Economic Summit and Illinois White Nationalist Meet-and-Greet was taking place. The White Nationalists were targeted inside the restaurant and physically attacked, causing several injuries and completely shutting down their meeting. The anti-fascist group was privy to anonymous inside information. This fascist event had been in secret planning for six months. The attendees have attempted to cover up the true intent of the event with mainstream media reports initially reporting the white nationalist conference as a wedding party and then as an Irish heritage meeting. The event was advertised on www.stormfront.org, an established white nationalist fascist internet forum.

Tinley Park Mayor Ed Zabrocki told the Chicago Tribune late Saturday that authorities were not certain about connections between the groups or the attackers' motivations.

The Tribune reported three of the injured were taken to the hospital. Others refused medical attention.
